An important study maps how nerves control the Drosophila male reproductive tract, revealing two types of glutamatergic neurons that also release serotonin or octopamine.

Thanks @elife.bsky.social for this thread on @brunolemaitre.bsky.social and all's immense work assessing the field's reliability!

For #Metascience folks: what's unique about the #Drosophila model is access to independent tools. Most studies use multiple approaches to test their key questions.

1/ A field-wide audit of reproducibility in Drosophila immunity

The ReproSci project assessed how many claims from 400 papers had been verified by later research, and, in an accompanying study, tested those that remained uncorroborated.

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)
